So I clearly know what it looks like and just as clearly don't see it in either THX, ISF night or ISF day (nor did Kevin Miller). I think there are many other owners that fit into this category. You can also put all the professional reviewers in this same category as it's never (or rarely) commented on nor does it serve to detract from the reviewer's overall stellar rating of the set.
So I do believe there are other issues involved in the manifestation of this problem. What they are I can't say for sure, but I wouldn't rule out other equipment in the chain, calibrations or sample to sample variation.
But there is zero question in my mind that to say that every set has it and it can be seen in every mode, is simply inaccurate.
The magnitude of the problem is proportional to the number of times you see it while watching TV. Luckily enough for you its only when you are looking for the problem that you see it.
I doubt its a piece of equipment, because at least for me I tried two different players. The only commonality was power (though considering the Elite's pickiness when it comes to UPS maybe that does factor in). I doubt its a sample to sample issue. If these were broken sets than statistically someone would have had the problem go away with a replacement set. This is why I believe every set has the problem.
How noticeable it is varies heavily on the sample, calibration settings and ambient light. I don't believe that THX mode has some sort of magic code in it that prevents the pulsing. More likely your movie mode settings exacerbate the problem to where you notice it. The bug could still be there in THX mode but below perception (and thus not a problem). I'm not sure what sample you use to look at the problem, but every sample has the problem to different magnitudes. I never watched TDK on the Elite so I can't judge. Ambient light plays such a role that when the sun is out the same content and same settings that create the worst flickering at night isn't noticeable at all. The flickering isn't gone, I just can't see it. Unfortunately I did most of my watching in the dark.
I stand by my assertion that every set has the bug. We also agree that its not noticeable by everyone in every mode, though my belief is that its there and below perception. I'll bet that the 'darker than black' sample will flicker on any calibrated set (local dimming = 'on') in any mode in a dark room.
